# MBR0540

**Shikues** · Schottky Diodes · SOD-123

MBR0540 from Shikues, in a SOD-123. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Cathode | passive | Cathode terminal of the Schottky barrier diode; the datasheet rates the device at 350 mA average forward rectified current and 400 mW power dissipation. |
| 2 | Anode | passive | Anode terminal of the Schottky barrier diode, forming the forward-conduction path to the cathode (pin 1) in the SOD-123 package. |

## CAD (KiCad official)

- Symbol: `MBR0540`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123 (KiCad packages3D, STEP)
- 3D model files: `mbr0540-etched.step` / `mbr0540-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mbr0540.step` / `mbr0540.glb` are the bare package body.
